Hello Flipper community,
I hope you can help me with this issue - I was recently trying to capture my pretty old LiftMaster garage door opener signal (I don’t know the specific model number). I am almost positive that it uses static codes to operate, considering how old it is and that I added the key to Hyundai HomeLink without having to press any button on the unit itself. I tried to capture the signal from the opener and HomeLink with my Flipper multiple times using both the Read and Read RAW functions, to no avail. I have used the frequency analyzer function to see that my remote was somewhere in the 390 MHz range. I set it to that and tried both AM modulation frequencies and even varied the signal a bit with no success. On the Read RAW function, my Flipper will see the signal but when trying to replay it will not open the garage. On the Read function, I saw the little bar at the bottom go up a bit but no signal came up. Then, I tried to capture the Hyundai HomeLink signal. First, I tried to use the 390 MHz range and got nothing. Then, I used the Frequency Analyzer and got ~312 MHz. I tried both AM modulations and tried varying the frequency a bit, but no signal came up in the end. Any way you could help?
Give us pictures of the remote. Preferable external and internal.
Does the remote show an FCC ID? If so give it us.
Is this how you programmed homelink? If not give us the process.
Thanks for your response! I will get back to you in the morning. Once again thanks a ton!
Thank you! I will attach photos. I tried searching for an FCC ID, and I found a number that I thought to be the FCC ID, so I looked up the number up on the official FCC ID lookup tool. I tried a few different combinations on where the letters and numbers go, although could not find anything. Here is what I believe to be the FCC ID: 031D0385. I don’t know exactly how HomeLink was programmed as it was not my car although I believe the description that was given to me was like this but without pressing any button on the motor itself. I watched the official HomeLink programming video and it seems that that step is only necessary if you have a rolling code garage door opener, which I am pretty sure that I do not. Thank you very much!
The Official FCC search tool is a pain. Instead I use fcc.id because we can use it to link.
031D0385 isn’t the FCC id but at least it’s a part number. I have a meeting but I’ll take another look at this later. I think I found the FCC id which confirms the frequency.
Thank you so much!!! I really appreciate your help here, and take your time on this. One question though: I am definitely not a pro with this website, but it says that it is a Supersonic thing. I would assume that it would say LiftMaster there, so is Supersonic just the remote manufacturer? Once again, Thank you very much!
You are correct I seem to have found the generic version made by another company. It appears the color of your learn button is helpful. Can you tell which you have?
An opener with a red or orange learn button operates at 390 megahertz using Security+ Rolling Code technology**. An opener with a green learn button also uses 390 megahertz, but it operates on Billion Code technology. Openers with purple learn buttons operate at 315 megahertz using Security+ Rolling Code technology.
I am not at home right now, although I can provide some info right now. I do not believe that I have a learn button, as I believe that my garage door uses static codes. I checked, and I do not think I have a learn button. I will try to get a better look later.
A lot of static remotes ship with a preprogrammed code but no two are the same. My understanding is the green learn button on the garage opener means it’s static but each remote has it’s own code(one of a “billion” codes). The garage can learn several remotes with different static codes. The other type of static garage opener uses dip switches to select a code.
Ok, I think I understand now. Thank you! One question though: can’t the car just copy the code that is being sent by the remote and replay it? Is it changing the code when it captures it, signifying why it needs the “learn” button? Once again, thank you very much!
As long as the code is static the car can copy the code and the Flipper probably can as well. There are remotes that copy the code from the original remote for convenience but it’s more secure for the garage opener to learn the remote. It’s better for security if each remote has a unique code in case one is lost.
Ok, Thank you! So how can I copy it with the Flipper?
If it’s a green button You should be able to read raw 390mhz. If it’s one of the other colors you need to use the add manually process.
Ok, I will work on this tomorrow. Thank you!
So… let’s say it’s been more than a day. I was revisiting this, and I found that my opener has a green button. So now would I have to pair the code that I copied to the opener? Sorry for the trouble and VERY late response.
Based on what I remember you don’t need to pair the code. You should be able to copy the code from the remote and replay it.
Thank you. So for whatever reason, (and I’m sorry about this), I managed to skip over the main issue entirely in my original post! The issue is that I can capture the signal perfectly fine, but when I send it the door isn’t opening. I can send you a video or something if you would like!
How are you capturing the code? There are a couple different ways so that matters.
I am capturing the code using the Read RAW function with the frequency settings set to 390 MHz, Modulation AM650. There is no RSSI limit in place.
See if AM270 works.
